Abstract (en)

[origin: EP0945963A2] Two rotors (3,4) and one stator (2) are arranged coaxially in a three layer construction. A coil unit comprising plural coils (6) arranged at equal angular intervals on a stator (2) is provided. The coil unit forms rotating magnetic fields of identical number to the magnetic pole number of the first rotor (3) according to a first alternating current, and forms rotating magnetic fields of identical number to the magnetic pole number of the second rotor (4) according to a second alternating current. Plural rotors (3, 4) are driven by a single coil unit by supplying a composite current of the first and second alternating currents to the coil unit. <IMAGE>
